Tawhid al-Rububiyyah refers to the Islamic concept of the oneness of God's lordship. It emphasizes that there is only one Allah who is the creator, sustainer, and ruler of the universe. This belief asserts that all aspects of existence, including life and death, are under the control of this singular divine entity. This principle is foundational in Islam, distinguishing it from polytheistic beliefs. By affirming Tawhid al-Rububiyyah, Muslims acknowledge that no other beings or forces share in God's authority or power. This understanding reinforces the importance of worshiping only Allah and recognizing His unique role in the cosmos.
